Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a UAV and a wearable device. Background Technology

[0002] Drones, or unmanned aerial vehicles, have been widely used in many fields in recent years due to their unique aerial perspective and flexible operation. As the application scenarios of drones continue to expand, their safety issues are becoming increasingly prominent. Wearable devices are intelligent devices that integrate multiple cutting-edge technologies such as sensors, microprocessors, and wireless communication. They can fit closely to the human body and collect human physiological data and environmental information in real time.

[0003] The patent with publication number CN206282146U relates to a drone and a wearable device. The drone includes: a fuselage, a flight control board mounted on the fuselage, and support arms on the fuselage. The support arms are equipped with motors and propellers. The motors drive the propellers connected to them to rotate. Each support arm is equipped with a sound sensor, which is connected to the flight control board to collect sound signals from the propellers during operation. The flight control board includes: a signal acquisition unit for acquiring the sound signals collected by the sound sensors; and a flight status determination unit for processing the sound signals to obtain the current operating status of the propellers and determining the flight status of the drone based on the operating status of the propellers. By installing sound sensors on the drone's support arm to collect the sound signals from the propellers and then calculating the drone's flight status, it is easier to control the drone's flight and improve its controllability and safety. However, while this device collects the propeller sound signals and calculates the drone's flight status to improve controllability and safety, it is difficult to ensure that the sensor and the receiving device are aligned during flight. This reduces the device's operational accuracy and can easily cause signal loss when the drone is in a blind spot, leading to reduced stability and flight accidents. Therefore, a drone and wearable device are proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a drone and a wearable device in response to the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a drone and a wearable device, including a housing, an extension frame rotatably connected to the inner wall of the housing, a rotating shaft rotatably connected to the inner wall of the extension frame, a fan blade fixedly connected to the top of the rotating shaft, a sound wave sensor rotatably connected to the inner wall of the extension frame, a gear fixedly connected to the circumferential surface of the sound wave sensor, an electric push rod fixedly connected to the inner wall of the extension frame, a rack fixedly connected to the output end of the electric push rod, an anti-vibration mechanism to prevent internal parts from shaking during operation on the inner wall of the extension frame, and an anti-accidental injury mechanism to prevent workers from being cut on the housing. A camera is installed on the inner wall. A long rod is fixedly connected to the bottom of the casing. A sliding plate is slidably connected to the circumference of the long rod through a spring. Hinge rods are hinged to both sides of the sliding plate. A support frame is rotatably connected to the bottom of the casing through a torsion spring. Before takeoff, an electric push rod drives the acoustic sensor to rotate 90 degrees, so that the sensor head of the acoustic sensor is still facing the ground when it takes off into the air. This further improves the operational accuracy of the equipment and is a key means to achieve safe landing, precise hovering, terrain following and all-round perception. It can maintain reliable operation in environments where GPS is unavailable, lighting is limited or complex, and make the operation of the equipment more stable. A motor is fixedly connected to the inner wall of the extension frame, and the output end of the motor is fixedly connected to the bottom of the rotating shaft. The rack is slidably connected to the inner wall of the extension frame, and the bottom of the rack contacts the circumferential surface of the gear. The support frame is hinged to the bottom of the hinge rod near the long rod. The sliding plate moves along the movement trajectory of the long rod. An infrared sensor is installed inside the housing, and a dynamic sensor is installed on the inner wall of the camera. When the drone finishes its work, the sliding plate is pulled down along the long rod by the hinge rod through the hinge point. The spring between the sliding plate and the long rod provides buffering, which can quickly decelerate the drone when it loses control or malfunctions, greatly reducing the impact force and significantly reducing the probability of damage to key components such as the fuselage, propellers, and sensors.

[0006] Preferably, the anti-shake mechanism includes a sliding bar, a connecting shell is fixedly connected to the bottom of the sliding bar, a wheel is rotatably connected to the inner wall of the connecting shell, and a limit plate is fixedly connected to the top of the acoustic sensor. When taking off, the acoustic sensor drives the wheel and the limit plate to lock in place, maintaining stability in a high-dynamic flight environment and avoiding data distortion or hardware damage caused by loosening, thus providing a stable and reliable sensing basis. The top of the sliding plate is hinged to a connecting rod, and the bottom of the housing is fixedly connected to a fixed plate. The inner wall of the fixed plate is slidably connected to a movable plate. The inner wall of the fixed plate is slidably connected to a partition via a spring. An L-shaped rod is fixedly connected to the left side of the partition, and a sliding cylinder is rotatably connected to the inner wall of the L-shaped rod. The circumferential surface of the sliding rod is slidably connected to the inner wall of the extension frame via a spring, and the connecting shell moves along the movement trajectory of the sliding rod. The circumferential surface of the wheel contacts the outer surface of the limiting plate. The bottom of the movable plate is hinged to the top of the connecting rod, and the movable plate moves along the movement trajectory of the sliding cylinder. The circumferential surface of the sliding cylinder contacts the bottom of the housing. When the device slowly lands, the weight of the drone itself will press down the sliding plate, causing it to move downwards. The sliding plate will then drive the partition to open the charging port of the housing. The automatic opening mechanism detects the removal of the charging gun, avoiding human error, reducing maintenance and replacement costs, preventing accidental collisions or short circuits during the opening process, and improving the safety of the recovery process.

[0007] Preferably, the anti-accidental injury mechanism includes a movable rod, a trapezoidal block is fixedly connected to the top of the movable rod, and an inclined block is fixedly connected to the bottom of the casing. When taking off, the partition drives the trapezoidal block to cooperate with the inclined block to lock itself, which can effectively prevent others from pulling out the charging gun at will during the charging process, reduce the risk of electric shock and theft, not only significantly improve safety, but also extend the interface life, reduce maintenance costs, and improve user convenience. The inner wall of the extension frame is slidably connected to a compression rod via a spring. A speed reduction plate is fixedly connected to the top of the compression rod. A limit plate is fixedly connected to the top of the extension frame. An elastic telescopic rod is fixedly connected to the circumferential surface of the rotating shaft. A pulley is rotatably connected to the inner wall of the elastic telescopic rod. The circumferential surface of the moving rod is slidably connected to the inner wall of the partition via a spring. The trapezoidal block moves on the trajectory of the inclined block. The bottom of the limit plate contacts the top of the extension frame. The inner wall of the limit plate contacts the speed reduction plate. When the UAV stops working, the fuselage moves downward, causing the extension frame to move downward. The extension frame drives the pulley to decelerate the fan blades, preventing the speed from being too fast and damaging the wearer's hand. This can significantly reduce the descent speed and reduce the impact force, thereby protecting the fuselage and key components. The flight control system can better control the vertical speed and attitude, enabling the UAV to achieve a soft landing at the target location, especially in narrow or uneven terrain, where a safe landing is easier to complete.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This drone and wearable device, through the coordinated operation of its casing, extension frame, fan blades, rotating shaft, camera, acoustic sensor, electric push rod, rack, gear, support frame, long rod, sliding plate, and articulated rod, allows the acoustic sensor to rotate 90 degrees via the electric push rod before takeoff. This ensures that the sensor head remains pointed towards the ground when the drone is airborne, further improving the device's operational accuracy. This is a key means to achieve safe landing, precise hovering, terrain following, and all-around perception. It can maintain reliable operation in environments where GPS is unavailable, lighting is limited, or complex environments, making the device's operation more stable. After the drone finishes its work, the articulated rod moves, pulling the sliding plate down the long rod through the hinge point. The spring between the sliding plate and the long rod provides cushioning, enabling rapid deceleration in the event of drone loss of control or malfunction, significantly reducing the impact force and the probability of damage to key components such as the fuselage, propellers, and sensors. 2. This drone and wearable device, through the coordinated operation of the sliding stick, connecting shell, wheel, and limiting plate, when taking off, the acoustic sensor drives the wheel and the limiting plate to self-lock, maintaining stability in a highly dynamic flight environment and avoiding data distortion or hardware damage caused by loosening, thus providing a stable and reliable sensing foundation; 3. This drone and wearable device, through the coordinated operation of connecting rods, fixed plates, moving plates, L-shaped rods, sliding cylinders, and partitions, when the device slowly lands, the weight of the drone itself will press down the sliding plate to move it down. The sliding plate will drive the partition to open the charging port of the casing. The automatic opening mechanism detects the removal of the charging gun, avoiding human error, reducing maintenance and replacement costs, preventing accidental collisions or short circuits during the opening process, and improving the safety of the recovery process. 4. This drone and wearable device, through the coordinated operation of the lever, trapezoidal block and inclined block, when taking off, the partition drives the trapezoidal block to cooperate with the inclined block to lock itself, which can effectively prevent others from arbitrarily pulling out the charging gun during charging, reducing the risk of electric shock and theft. It can not only significantly improve safety, but also extend the interface life, reduce maintenance costs and improve user convenience. 5. This drone and wearable device, through the coordinated operation of the compression rod, speed reducer, limit plate, elastic telescopic rod, and pulley, allows the fuselage to move downwards when the drone stops working, causing the extension frame to move downwards as well. The extension frame then drives the pulley to slow down the fan blades, preventing excessive rotation speed from injuring the wearer's hand. This significantly reduces the descent speed and impact force, thereby protecting the fuselage and critical components. The flight control system can better control the vertical speed and attitude, enabling the drone to achieve a soft landing at the target location, especially in narrow or uneven terrain where a safe landing is easier.

[0011] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0012] Please see Figures 1-8One embodiment of the present invention is as follows: a drone and a wearable device, including a housing 1, an extension frame 2 rotatably connected to the inner wall of the housing 1, a rotating shaft 4 rotatably connected to the inner wall of the extension frame 2, a fan blade 3 fixedly connected to the top of the rotating shaft 4, a sound wave sensor 6 rotatably connected to the inner wall of the extension frame 2, a gear 11 fixedly connected to the circumferential surface of the sound wave sensor 6, an electric push rod 9 fixedly connected to the inner wall of the extension frame 2, a rack 10 fixedly connected to the output end of the electric push rod 9, an anti-vibration mechanism 7 for preventing internal parts from shaking during operation, an anti-accidental injury mechanism 8 for preventing workers from being cut, a camera 5 installed on the inner wall of the housing 1, a long rod 13 fixedly connected to the bottom of the housing 1, a sliding plate 14 slidably connected to the circumferential surface of the long rod 13 by a spring, hinge rods 15 hinged to both sides of the sliding plate 14, and a support frame 12 rotatably connected to the bottom of the housing 1 by a torsion spring. Once the operator has donned the wireless wearable device for the drone, simply connect the device and the drone will fly using the sensors between the device and the drone. Before takeoff, the device worn by the operator emits sound waves. The sound wave sensor 6 receives these sound waves, activating the motors inside the extension frame 2. During operation, the speed can be controlled by receiving signals from the sound wave sensor 6, and the drone's attitude in the air can be controlled by the infrared sensor on the wearer. Combined with the dynamic sensor inside the camera 5, this allows for faster capture and tracking of flying objects. Before takeoff... First, the electric push rod 9 on the inner wall of the extension frame 2 is activated by the device. The electric push rod 9 drives the rack 10 to move through the output end. The rack 10 moves and meshes with the circumferential surface of the gear 11 at the bottom, thereby driving the gear 11 to rotate. The gear 11 will drive the acoustic sensor 6 to rotate 90 degrees, so that when the acoustic sensor 6 takes off into the air, the sensor head of the sensor is still facing the ground, which further improves the operating accuracy of the device. It is a key means to achieve safe landing, precise hovering, terrain following and all-round perception. It can maintain reliable operation in environments where GPS is unavailable, light is limited or complex, and make the operation of the device more stable. A motor is fixedly connected to the inner wall of the extension frame 2. The output end of the motor is fixedly connected to the bottom of the rotating shaft 4. The rack 10 is slidably connected to the inner wall of the extension frame 2. The bottom of the rack 10 is in contact with the circumferential surface of the gear 11. The support frame 12 is hinged to the bottom of the hinge rod 15 on the side near the long rod 13. The sliding plate 14 moves on the movement trajectory of the long rod 13. An infrared sensor is installed inside the housing 1. A dynamic sensor is installed on the inner wall of the camera 5. After the drone finishes its work, the acoustic sensor 6 controls the fan blades 3 to operate, causing the fan blades 3 to slowly bring the casing 1 to the ground. As the casing 1 moves down, it causes the support frame 12 to move down as well. At this point, the support frame 12 will make contact with the ground, and the torsion spring will cause the support frame 12 to rotate downwards. The rotation of the support frame 12 will pull the hinge rod 15 to move through the hinge point. The movement of the hinge rod 15 will pull the sliding plate 14 to move down along the long rod 13 through the hinge point. The spring between the sliding plate 14 and the long rod 13 will provide buffering, which can quickly decelerate the drone in the event of loss of control or malfunction, greatly reducing the impact force and significantly reducing the probability of damage to key components such as the fuselage, propellers, and sensors.

[0013] Working principle: Before takeoff, the electric push rod 9 drives the acoustic sensor 6 to rotate 90 degrees, so that when the acoustic sensor 6 takes off, the sensor head is still pointed at the ground, which further improves the operation accuracy of the equipment and is a key means to achieve safe landing, precise hovering, terrain following and all-round perception, making the operation of the equipment more stable. After the drone finishes its work, the hinge rod 15 moves and pulls the sliding plate 14 down along the long rod 13 through the hinge point. The spring between the sliding plate 14 and the long rod 13 provides buffering, which can quickly decelerate the drone in case of loss of control or malfunction, and greatly reduce the impact force.

[0014] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, the anti-shake mechanism 7 includes a sliding rod 71, a connecting shell 72 is fixedly connected to the bottom of the sliding rod 71, a wheel 73 is rotatably connected to the inner wall of the connecting shell 72, and a limit plate 74 is fixedly connected to the top of the sound wave sensor 6. During takeoff, the acoustic sensor 6 is first flipped by the electric push rod 9. This flipping of the acoustic sensor 6 simultaneously rotates the limiting plate 74. The rotation of the limiting plate 74 causes the inclined surface to contact the circumferential surface of the wheel 73, thereby moving the wheel 73. The wheel 73 then moves the connecting shell 72. When the limiting plate 74 enters the interior of the connecting shell 72, the sliding rod 71, through the spring between it and the extension frame 2, resets the connecting shell 72. This, in turn, resets the wheel 73. The engagement between the wheel 73 and the limiting plate 74 enables the acoustic sensor 6 to self-lock in position, maintaining stability in a highly dynamic flight environment and preventing data distortion or hardware damage due to loosening. This provides a stable and reliable sensing foundation. A connecting rod 75 is hinged to the top of the sliding plate 14, and a fixed plate 76 is fixedly connected to the bottom of the housing 1. A movable plate 77 is slidably connected to the inner wall of the fixed plate 76. A partition 710 is slidably connected to the inner wall of the fixed plate 76 via a spring. An L-shaped rod 78 is fixedly connected to the left side of the partition 710. A sliding cylinder 79 is rotatably connected to the inner wall of the L-shaped rod 78. The circumferential surface of the sliding rod 71 is slidably connected to the inner wall of the extension frame 2 via a spring, and the connecting shell 72 moves on the movement trajectory of the sliding rod 71. The circumferential surface of the wheel 73 contacts the outer surface of the limiting plate 74. The bottom of the movable plate 77 is hinged to the top of the connecting rod 75, and the movable plate 77 moves on the movement trajectory of the sliding cylinder 79. The circumferential surface of the sliding cylinder 79 contacts the bottom of the housing 1. As the device slowly lands, the drone's own weight will cause the sliding plate 14 to move downwards. The sliding plate 14 will then move the connecting rod 75. The movement of the connecting rod 75 will cause the moving plate 77 to move through the hinge point. The moving plate 77 moves along the moving trajectory of the sliding cylinder 79, so that the contact surface leaves the sliding cylinder 79. The sliding cylinder 79 will then move the partition 710 through the spring between it and the fixed plate 76, thereby causing the partition 710 to open the charging port of the housing 1. The automatic opening mechanism detects the removal of the gun, avoiding human error, reducing maintenance and replacement costs, preventing accidental collisions or short circuits during the opening process, and improving the safety of the recovery process.

[0015] Working principle: During takeoff, the acoustic sensor 6 drives the wheel 73 to lock in place with the limiting plate 74, maintaining stability in a high-dynamic flight environment and preventing data distortion or hardware damage caused by loosening, thus providing a stable and reliable sensing foundation. When the device lands slowly, the weight of the drone itself will push the sliding plate 14 down, which will drive the partition 710 to open the charging port of the casing 1. The automatic opening mechanism detects the removal of the charging gun, avoiding human error and reducing maintenance and replacement costs.

[0016] The anti-accidental injury mechanism 8 includes a movable rod 81, a trapezoidal block 82 fixedly connected to the top of the movable rod 81, and an inclined block 83 fixedly connected to the bottom of the housing 1. During takeoff, the sliding cylinder 79 moves upward via the sliding plate 14, thereby pushing the partition 710 to close the charging port of the housing 1. Simultaneously, the movement of the partition 710 drives the moving rod 81 to move, which in turn drives the trapezoidal block 82 to move. The trapezoidal block 82 then contacts the inclined surface of the inclined block 83, causing it to move further. When the trapezoidal block 82 leaves the inclined block 83, it rebounds through the spring between it and the partition 710. Thus, the trapezoidal block 82, in conjunction with the inclined block 83, locks the partition 710, effectively preventing others from arbitrarily removing the charging gun during charging, reducing the risk of electric shock and theft. This not only significantly improves security but also extends the interface lifespan, reduces maintenance costs, and enhances user convenience. The inner wall of the extension frame 2 is slidably connected to a compression rod 84 via a spring. A speed reduction plate 85 is fixedly connected to the top of the compression rod 84. A limit plate 86 is fixedly connected to the top of the extension frame 2. An elastic telescopic rod 87 is fixedly connected to the circumferential surface of the rotating shaft 4. A pulley 88 is rotatably connected to the inner wall of the elastic telescopic rod 87. The circumferential surface of the moving rod 81 is slidably connected to the inner wall of the partition 710 via a spring. The trapezoidal block 82 moves on the movement trajectory of the inclined block 83. The bottom of the limit plate 86 contacts the top of the extension frame 2. The inner wall of the limit plate 86 contacts the speed reduction plate 85. When the drone stops working, the casing 1 moves downward, causing the extension frame 2 to move downward. The extension frame 2 then moves the compression rod 84 downward, and the compression rod 84 moves downward and contacts the ground. This causes the speed reduction plate 85 to move upward along the limit plate 86, so that the speed reduction plate 85 contacts the pulley 88. At this time, the rotating shaft 4 rotates slowly, and the rotating shaft 4 drives the elastic telescopic rod 87 to rotate. The elastic telescopic rod 87 drives the pulley 88, and the pulley 88 contacts the inner wall of the speed reduction plate 85. The pulley 88 will decelerate through the elastic telescopic end of the elastic telescopic rod 87, thereby decelerating the fan blade 3 and preventing the wearer's hand from being damaged by excessive speed. It can significantly reduce the falling speed and reduce the impact force, thereby protecting the body and key components. The flight control system can better control the vertical speed and attitude, enabling the drone to achieve a soft landing at the target position, especially in narrow or uneven terrain, where it is easier to complete a safe landing.

[0017] Working principle: When taking off, the partition 710 drives the trapezoidal block 82 to cooperate with the inclined block 83 to lock itself, which can effectively prevent others from pulling out the charging gun at will during charging, reducing the risk of electric shock and theft. It can not only significantly improve safety, but also extend the life of the interface. When the drone stops working, the shell 1 moves down, which drives the extension frame 2 to move down. The extension frame 2 drives the pulley 88 to decelerate the fan blade 3, avoiding damage to the wearer's hand due to excessive speed. It can significantly reduce the falling speed and reduce the impact force, thereby protecting the body and key components, enabling the drone to achieve a soft landing at the target location, especially in narrow or uneven areas where it is easier to complete a safe landing.

[0018] This invention provides a drone and a wearable device. Many methods and approaches exist for implementing this technical solution; the above description is merely a preferred embodiment. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention. All components not explicitly stated in this embodiment can be implemented using existing technologies.
